1. DNA contains genetic instructions that are passed from parents to offspring. DNA can be manipulated through genetic engineering techniques like cloning.
2. Gene cloning involves inserting DNA from one organism into a vector then introducing it into a host cell where it can be replicated. This allows genes to be transferred between organisms.
3. Genetically modified organisms are produced through gene cloning and can have modified traits like delayed ripening or pest resistance. While GMOs have benefits, some are concerned about their long term impacts.
